Document Summary

Stem cells: immature cells whose final role is based on the chemical environment in which is develops.

Neuroplasticity: the capacity of the brain to change and rewire itself based on individual experience. Ex. occipital lobs of blind people are used for non-visual purposes.

Some animals with simple brains and spinal cord (ex. fish) have lifelong regeneration ability of their cn (cid:449)he(cid:374) it"s da(cid:373)aged. Create new tissue to replace the damaged ones. Trophic factors (chemical growth factors) can stimulate the growth of new dendrites and axons. Only a few regions can form new neurons in adulthood (ex. hippocampus) Limited by presence of chemicals that inhibit growth of new axons around damaged area: prevents the brain from forming incorrect connections between brain areas, may produce larger behavioural problems than initially done.
